The Graphite version now available for $39.95 (down from $49.95), and the prices of the Walnut and Gold editions have been slashed to $49.95 from their usual retail price of $59.95. Last year, FiftyThree launched a Software Development Kit for the stylus, giving third-party developers the ability to build in support for features such as palm rejection, erase, and blend into their own apps. The list of Pencil-ready apps currently include Autodesk's Sketchbook, Adobe's creative utilities, Procreate, Noteshelf and much more.
